1944309-1	1991	The 3 beta-hydroxysteroid dehydrogenase/delta 5-delta 4 isomerase (3 beta HSD) enzyme catalyzes the oxidation and isomerization of delta 5-3 beta-hydroxysteroid precursors into delta 4-ketosteroids, thus leading to the formation of all classes of steroid hormones.	Steroids	247-263	hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1	Homo sapiens	67-77
